Only brain mri ???


Can anyone tell me, why the majority of the time you only get brain scans and not spinal ones. Is the brain where most of the lesions are ??? I have about 20 lesions i would say on my brain, not sure about spine. Diagnosed in 2010. Started dmds about 4/ 5 years ago approximately. Started on copaxone , now on Tecfidera.

Hi, it took 22 years to diagnose me. No brain lesions, just 2 hiding in my spine.
